Trunnion and bracket for rollers

Abstract

A universal trunnion and bracket system for shade rollers in which the bracket is aligned with the centerline of the roller. The trunnion is rotatably mounted in an end of the roller. A lug, offset from the centerline of both the trunion and the roller, protrudes from the trunnion. The bracket has several (usually three) slots with tapered sides to match the tapered sides of the lug. The roller is mounted to the bracket by lowering the end of the roller until the lug engages a slot in the bracket, the non-circular shape of the lug and the slot preventing rotation of the trunnion with respect to the bracket.

I claim: 
     
       1. A bracket and trunnion means hardware pair for the trunnion end of a roller, said trunnion means being adapted for rotatable mounting into an end of said roller, a protruding lug displaced away from the centerline of said trunnion means for engaging said bracket to mount said roller, the cross-sectional shape of said lug being non-circular to impede rotation of said lug with respect to said bracket, said bracket having at least one slot for engaging said lug. 
     
     
       2. A bracket and trunnion means hardware pair in accordance with claim 1 in which said trunnion means includes a housing and trunnion insert therefor adapted for rotatable mounting within the housing, said housing being sized for fitting tightly into an end of a roller and said lug extending from the end of the said trunnion insert. 
     
     
       3. A bracket and trunnion means hardware pair in accordance with claim 1 in which said bracket has a mounting flange. 
     
     
       4. A bracket and trunnion means hardware pair in accordance with claim 1 in which said bracket has a first slot for engaging said lug when said bracket is mounted to a vertical wall and at one end of said roller and a second slot for engaging said lug when said bracket is mounted to a vertical wall and at the second end of said roller. 
     
     
       5. A bracket and trunnion means hardware pair in accordance with claim 4 in which the axis of symmetry of said bracket intersects the axis of symmetry of said roller when said lug is engaged by either of said slots. 
     
     
       6. A bracket and trunnion means hardware pair in accordance with claim 5 further incorporating a slot for engaging said lug when said bracket is mounted to a horizontal surface.
